Dynamic Drive Overlay
Dynamic Drive Overlay is software that overwrites a computer's system BIOS.
Electrostatic Discharge
The rapid change in electrical energy caused by static electricity. This can damage or destroy electronic
equipment or hardware. Prevention consists of grounding oneself before handling any electronic
equipment.
FAT16/FAT32 (File Allocation Table)
The file allocation table is a group of sectors in a hard drive that contains address chains for the different
files on a hard disk drive. There are usually two FATs (kept in different locations) on a hard drive.
FAT32 is available in the Windows® 95 & Windows® 98 operating systems. FAT32 receives its
designation because it allows 32 bits of addressing as opposed to 16 bits in the FAT16 file system.
FDISK
FDISK is a program run in DOS that allows a user to partition a hard disk drive. Partitioning your hard
disk drive is essential for it to work properly.
Format
When a hard disk is formatted, the computer writes a magnetic track pattern onto a disk surface,
specifying the locations of the tracks and sectors. This information must exist on a hard disk before it
can store data.
FTP (File Transfer Protocol)
In the Internet suite of protocols, an application layer protocol that uses TCP and Telnet services to
transfer bulk-data files between machines or hosts.
Hard Disk Drive (HDD)
A stand alone disk drive that reads and writes data on rigid disks and can be attached to a port on the
system unit. Synonymous with fixed disk drive, hard drive.
Head
The tiny electromagnetic coil and metal pole used to create and read back magnetic patterns on the disk.
HPFS (High Performance File System)
HPFS is the file system used by OS/2.
IDE (Integrated Drive Electronics)
Also known as ATA (Advanced Technology Attachment) by ANSI. IDE technology was developed to
overcome CMOS limitations in older computers. IDE is used as one of the standard interfaces between a
computer's input/output devices and the motherboard. Although it can be used with other bus standards
the IDE interface was originally based on the IBM PC ISA16 bit bus standard. The nature of the IDE
interface allows for only two components to be attached to each bus; one designated master and the
other slave. The IDE bus is unterminated, therefore, an IDE cable cannot exceed 18 inches.
Interface
A hardware of software protocol (contained in the electronics of the disk controller and drive) that
manages the exchange of data between the hard disk drive and the computer. The most common
interfaces for small computer systems are ATA (IDE) and SCSI.
Jumpers and Jumper Settings
Jumpers are small pieces of plastic with a conductive center. Jumpers are used to connect pins on a
device to provide settings that are changeable by the user, but remain constant during operation.
